However, this fertilizer agglomeration breaking mechanism will break all the fertilizers put into the hopper, not only breaking up the agglomerated fertilizers, but also breaking up the normal granular fertilizers, resulting in the integrity of the fertilizer particles not meeting customer requirements.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0005] In order to improve or solve the technical problem in the prior art that a fertilizer crushing device easily leads to low integrity of fertilizer particles, the utility model provides a crushing funnel for fertilizer with high integrity of fertilizer particles.

[0006] The crushing funnel for fertilizer includes: a hopper body, which includes a screening wall and opposite inlet and outlet ends; a plurality of screening holes with predetermined apertures are provided on the screening wall; a guide member, which is arranged at the inlet end and can guide the fertilizer flowing into the inlet end to the screening wall; and a crushing agitator cage, which is arranged at the outlet end and can break up the agglomerated fertilizer flowing down from the screening wall.

[0007] The utility model is used for a crushing hopper for fertilizers, which includes a hopper body, a guide member and a crushing and stirring cage. The hopper body includes a screening wall, and fertilizers can flow into the hopper body from the inlet end, and impact the screening wall under the guidance of the guide member; the fertilizers on the screening wall flow toward the outlet end under the action of gravity, and during the flow, the granular fertilizers pass through the sieve holes on the screening wall and fall onto the silo or conveying device below, while the agglomerated fertilizers flow into the crushing and stirring cage along the screening wall, and after being crushed in the crushing and stirring cage, they fall onto the silo or conveying device below. Through the above-mentioned arrangement, the utility model is used for a crushing hopper for fertilizers, which can screen granular fertilizers and agglomerated fertilizers, avoid the crushing and stirring cage from crushing granular fertilizers, ensure the integrity of fertilizer particles, and the crushing and stirring cage does not need to crush the granular fertilizers, which can improve the working efficiency of the crushing hopper.

[0008] In the preferred technical solution of the crushing funnel for fertilizer, the angle between the screening wall and the horizontal plane is greater than 30° and less than or equal to 50°. Through the above setting, the fertilizer accumulation angle is generally not greater than 30°. By setting the angle between the screening wall and the horizontal plane to be greater than 30° and less than or equal to 50°, it can be ensured that the fertilizer will not accumulate on the screening wall, and will not slide too fast to cause a large amount of granular fertilizer to slide into the crushing and stirring cage, which can make the crushing funnel have a higher screening efficiency and take into account the integrity of the fertilizer particles.

[0009] In the preferred technical solution of the crushing funnel for fertilizer, the crushing agitator includes a screen arranged at the outlet end, a rotating shaft rotatably arranged in the screen, and stirring teeth arranged on the rotating shaft. Through the above arrangement, the screen can accommodate the agglomerated fertilizer flowing out from the outlet end; the stirring teeth and the rotating shaft are rotatably arranged in the screen, and the agglomerated fertilizer can be crushed, and the crushed fertilizer falls from the mesh of the screen.

[0010] In the preferred technical solution of the above-mentioned crushing funnel for fertilizer, a rubbing rod is provided on the end of the stirring teeth away from the rotating shaft, and the rubbing rod is arranged at intervals with the screen. Through the above-mentioned arrangement, when the rubbing rod and the screen are interlaced, the agglomerated fertilizer between the two will be squeezed and rubbed, so that the agglomerated fertilizer is easier to break. At the same time, the rubbing rod can fill the gap between adjacent stirring teeth, enhance the crushing efficiency of the agglomerated fertilizer, and thus improve the working efficiency of the crushing funnel.

[0011] In the preferred technical solution of the crushing funnel for fertilizers, the stirring teeth are arranged in multiple groups along the circumference of the rotating shaft, and each group of stirring teeth is arranged in multiple groups along the length direction of the rotating shaft; each group of stirring teeth is connected to a rubbing rod. Through the above arrangement, multiple groups of stirring teeth are arranged, and each group is provided with multiple teeth, which can improve the crushing efficiency of fertilizers; at the same time, each group of stirring teeth is connected to a rubbing rod, which can not only avoid gaps between adjacent stirring teeth, but also avoid bending or deformation of the stirring teeth during the crushing process, thereby improving the stability and reliability of the crushing and stirring cage.

[0012] In the preferred technical solution of the crushing funnel for fertilizer, power sources for driving the rotation are symmetrically arranged at both ends of the rotating shaft. Through the above arrangement, the power sources are symmetrically arranged at both ends of the rotating shaft, which can prevent the rotating shaft from deflecting or shaking during rotation, prevent the stirring teeth from damaging the screen, and improve the stability and reliability of the crushing and stirring cage.

[0013] In the preferred technical solution of the crushing funnel for fertilizer, the screening wall includes a first screening wall and a second screening wall arranged opposite to each other; the guide member includes a first guide wall and a second guide wall arranged at an angle; the first guide wall extends toward the first screening wall, and the second guide wall extends toward the second screening wall. Through the above arrangement, the guide member can guide the fertilizer entering the hopper body to the screening wall so as to screen the fertilizer.

[0014] In the preferred technical solution of the crushing funnel for fertilizer, the guide member extends along the length direction of the crushing and stirring cage; a plurality of reinforcing plates are arranged at intervals in the guide member. Through the above arrangement, the reinforcing plates can enhance the structural strength of the guide member to avoid deformation or damage when impacted by fertilizer, thereby ensuring that the fertilizer entering the hopper body can be stably and reliably guided to the screening wall.

[0015] In the preferred technical solution of the above-mentioned crushing funnel for fertilizer, the bucket body is connected to a mounting bracket capable of supporting it, and the mounting bracket includes side brackets arranged on opposite sides of the bucket body, and a support rod connected to the side brackets and supporting the bucket body. Through the above-mentioned arrangement, the side brackets can provide sufficient supporting force to prevent the bucket body from tilting or collapsing during use; the support rod can evenly distribute the weight of the bucket body to the side brackets, improve the stability of the bucket body, prevent the bucket body from tilting or overturning, and thus improve the stability and service life of the crushing funnel.

[0016] In the preferred technical solution of the crushing funnel for fertilizer, the side bracket is arc-shaped, and foot plates are arranged at both ends of the side bracket. Through the above arrangement, the arc structure has the characteristics of bearing large bending force and light weight compared with the frame structure, and can better bear the weight of the bucket body and the impact force of the fertilizer; the foot plates can increase the contact area between the side bracket and the ground, reduce the pressure of the crushing funnel on the ground, and thus improve the stability of the mounting bracket.

[0032] Figure 4 1 is a top view of an embodiment of the utility model for a crushing funnel for fertilizer. Figure 2 , Figure 3 and Figure 4 As shown, the bucket body 2 is generally funnel-shaped and has an inlet end 21 and an outlet end 22 opposite to each other. The inlet end 21 is a thick end, and the outlet end 22 is a thin end. Figure 3 In the orientation shown, the inlet end 21 is the upper end and the outlet end 22 is the thin end. In one or more embodiments, the bucket body 2 includes a screening wall 23 and a connecting wall 24, the screening wall 23 includes a first screening wall 231 and a second screening wall 232 arranged oppositely; the connecting wall 24 includes a first connecting wall 24 and a second connecting wall 24 arranged oppositely, and the first connecting wall 24, the first screening wall 231, the second connecting wall 24, and the second screening wall 232 are connected head to tail to form a bucket body 2 that is roughly in the shape of a square funnel. Alternatively, the bucket body 2 can be completely composed of the screening wall 23. Alternatively, the bucket body 2 can also be set to a circular funnel shape or other suitable shape. Further, the connecting wall 24 and the screening wall 23 can be welded and reinforced by angle steel. Further, the screening wall 23 can be composed of a manganese steel screen, and a plurality of screen holes with a predetermined aperture are opened on the screening wall 23. The predetermined aperture can be determined according to the size of the fertilizer particles, for example, the predetermined aperture can be set to 1.5 times or 2 times the diameter of the fertilizer particles or other suitable sizes. Further, the screening wall 23 can be fixed to the connecting wall 24 by a connection structure such as welding or bolt connection. Preferably, the first screening wall 231 and the second screening wall 232 abut against the support rod 12.

Preferably, the angle between the screening wall 23 and the horizontal plane is 40°. It can be understood that when the angle between the screening wall 23 and the horizontal plane is smaller, the flow speed of the fertilizer is slower and the contact area between the screening wall 23 and the fertilizer is larger; when the angle between the screening wall 23 and the horizontal plane is larger, the flow speed of the fertilizer is faster and the contact area between the screening wall 23 and the fertilizer is smaller; the faster the flow speed of the fertilizer, the larger the contact area between the screening wall 23 and the fertilizer, and the higher the screening efficiency of the fertilizer. The flow speed of the fertilizer and the contact area between the screening wall 23 and the fertilizer are comprehensively balanced, and when the angle between the screening wall 23 and the horizontal plane is 40°, the screening efficiency of the fertilizer is the highest. Alternatively, the angle between the screening wall 23 and the horizontal plane can be set to 32°, 45°, 50°, etc.
